Abstract

An organic light emitting diode (OLED) display includes a pixelated OLED display panel and a color-correction component disposed on the pixelated OLED display panel. The pixelated OLED display panel has a ratio of blue-to-red color mixing weights at 30 degrees of β030, and a ratio of blue-to-red color mixing weights at 45 degrees of β045, where β045≥β030≥1.05 and 1.5≥β045≥1.1. The color-correction component is configured such that a ratio of blue-to-red color mixing weights at 45 degrees of the display is β45 and a ratio of blue-to-red color mixing weights at 30 degrees of the display is β30, where β045−0.1≥β45≥2.1−β045 and β030−0.05≥β30≥2.05−β030. Methods of making OLED displays are described.
